Significance Statement: The characterization of plant immune mechanisms involved in the perception of carbohydrate-based structures recognized as DAMPs/MAMPs is needed to further understand plant disease resistance modulation. We show here that IGP1/CORK1, IGP3 and IGP4 LRR-MAL RKs are required for the perception of carbohydrate-based DAMPs β-1,4-D-(xylose) (XYL4) and 3-α-L-arabinofuranosyl-xylotetraose (XAXX), further expanding the function of these LRR-MAL RKs in plant glycan perception and immune activation.
